In electronic products, power supply is an indispensable key component, especially for computers. Stable power supply is an important factor to ensure the normal operation of computers. So, how many volts is the computer power supply? This article will give you an in-depth analysis of the voltage problem of computer power supply and take you to understand the relevant knowledge points of computer power supply.
Basic composition and function of computer power supply
1. Basic composition of computer power supply: Computer power supply mainly consists of input filtering, rectification, pulse filtering, voltage stabilization (including overvoltage, overcurrent, undervoltage, short circuit protection, etc.) and DC output.
2. Function of computer power supply: The main function of computer power supply is to convert AC power into DC power and provide stable power supply for various components of the computer.
Main voltage of computer power supply
1. ATX power supply standard voltage: The current mainstream computer power supply adopts the ATX power supply standard, and its main voltage output specifications are +3.3V, +5V, +12V and -12V, -5V, etc. Among them, +12V voltage is responsible for driving motherboards, hard disk drives and other devices, and is the main output voltage.
In addition, the output voltage of computers of different brands may vary to a certain extent. For each computer or power supply product, you can check the power label or use a multimeter to measure.
2. Other voltages: In addition to the standard voltage of the ATX power supply, some special devices or components may require specific voltages, such as some graphics cards may require auxiliary power supply interfaces to provide additional 6pin or 8pin voltages. But these voltages are mostly met by the main power supply of the motherboard or other core components.
The impact of the stability and quality of computer power supply on voltage
The stability and quality of computer power supply have a vital impact on the performance and life of the computer. High-quality power supply can provide stable voltage output to ensure the normal operation of various components of the computer. Inferior power supply may cause voltage fluctuations, affect computer performance, and even damage hardware. Therefore, when choosing a computer power supply, in addition to paying attention to power, you also need to pay attention to the stability and quality of the power supply.
How to choose and maintain a computer power supply
1. Choose a suitable power supply: When choosing a computer power supply, you should choose the right power and quality according to the configuration and needs of the computer. Generally speaking, power supply products with high brand awareness and good reputation are more trustworthy.
2. Maintain the computer power supply: In order to extend the service life of the computer power supply, you should regularly clean the dust inside the power supply and keep the power supply well cooled. In addition, avoid using the computer in a humid environment to prevent a short circuit in the power supply.
Summary
This article provides you with a detailed analysis of the voltage problem of the computer power supply, including the basic composition and function of the computer power supply, the main voltage, the impact of stability and quality on the voltage, and how to choose and maintain the computer power supply. In fact, the voltage of the computer power supply is a relatively complex issue, involving specific hardware and configuration.
In general, in order to ensure the stable operation of the computer and extend its service life, it is very important to choose a suitable power supply and maintain good usage habits. I hope that through the introduction of this article, you can have a deeper understanding of the voltage problem of the computer power supply
